By the end, you'll have a working Dnsfilter agent that can list all ip addresses in your network, retrieve billing information for your organization, get details for a specific filtering category through natural language commands. This guide will help you understand how to give your Google ADK agent real control over a Dnsfilter account through Composio's Dnsfilter MCP server. Before we dive in, let's take a quick look at the key ideas and tools involved. ## Also integrate Dnsfilter with - [OpenAI Agents SDK](https://composio.dev/toolkits/dnsfilter/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/dnsfilter/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/dnsfilter/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/dnsfilter/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/dnsfilter/framework/codex) - [OpenClaw](https://composio.dev/toolkits/dnsfilter/framework/openclaw) - [Hermes](https://composio.dev/toolkits/dnsfilter/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/dnsfilter/framework/cli) - [LangChain](https://composio.dev/toolkits/dnsfilter/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/dnsfilter/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/dnsfilter/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/dnsfilter/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/dnsfilter/framework/crew-ai) ## TL;DR Here's what you'll learn: - Get a Dnsfilter account set up and connected to Composio - Install the Google ADK and Composio packages - Create a Composio Tool Router session for Dnsfilter - Build an agent that connects to Dnsfilter through MCP - Interact with Dnsfilter using natural language ## What is Google ADK? Google ADK (Agents Development Kit) is Google's framework for building AI agents powered by Gemini models. It provides tools for creating agents that can use external services through the Model Context Protocol. Key features include: - Gemini Integration: Native support for Google's Gemini models - MCP Toolset: Built-in support for Model Context Protocol tools - Streamable HTTP: Connect to external services through streamable HTTP - CLI and Web UI: Run agents via command line or web interface ## What is the Dnsfilter MCP server, and what's possible with it? The Dnsfilter MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Dnsfilter account. It provides structured and secure access to your DNSFilter environment, so your agent can perform actions like listing IPs, retrieving categories, managing network devices, and accessing billing information on your behalf. - Comprehensive IP address management: Direct your agent to list, fetch, or create IP address entries for your networks, streamlining network administration. - Efficient category and content filtering: Have your agent retrieve details for specific filtering categories or list all available content categories to fine-tune organizational policies. - Network device inventory automation: Ask your agent to list all MAC addresses and applications in your environment, making it easy to keep track of connected devices and services. - Application category insight: Instantly access information about application categories or retrieve all application categories to stay updated on your filtering options. - Billing information access: Let your agent pull detailed billing information for your organization, supporting audits and automated reporting workflows. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `DNSFILTER_CREATE_IP_ADDRESS` | Create IP Address | Tool to create a new ip address in dnsfilter. use after confirming the target network id exists. | | `DNSFILTER_GET_APPLICATION_CATEGORY` | Get Application Category | Tool to get basic information of a specific application category. use when you need details for a given application category id. | | `DNSFILTER_GET_BILLING_INFORMATION` | Get Billing Information | Tool to retrieve basic billing information for an organization. use when you need to obtain billing details for reporting or automation tasks. | | `DNSFILTER_GET_CATEGORY` | Get Category | Tool to get basic information of a specific category. use when you need to retrieve details for a category by its id. | | `DNSFILTER_GET_IP_ADDRESS` | Get IP Address | Tool to get basic information of the specified ip address. use when you need to fetch metadata for a particular ip after authentication. | | `DNSFILTER_LIST_ALL_CATEGORIES` | List All Categories | Tool to list all categories including internal categories. use when you need the complete set of filtering categories. | | `DNSFILTER_LIST_ALL_IP_ADDRESSES` | List All IP Addresses | Tool to list all user-associated ip addresses. use when you need a comprehensive list of all ip address entries in your organization. | | `DNSFILTER_LIST_ALL_MAC_ADDRESSES` | List All MAC Addresses | Tool to list all mac addresses with basic information. use when you need to retrieve all mac address entries in your organization. | | `DNSFILTER_LIST_APPLICATION_CATEGORIES` | List Application Categories | Tool to list application categories with basic information. use after authentication to retrieve all categories. | | `DNSFILTER_LIST_APPLICATIONS` | List Applications | Tool to list applications with basic information. use when you need to retrieve all applications for your dnsfilter organization. | | `DNSFILTER_LIST_BLOCK_PAGES` | List Block Pages | Tool to list block pages associated with the current user. use when you need to retrieve all block pages for review or update. | | `DNSFILTER_LIST_CATEGORIES` | List Categories | Tool to list categories with basic information. use when retrieving all dnsfilter categories for policy configuration. | | `DNSFILTER_LIST_INVOICES` | List Invoices | Tool to list invoices for an organization, most recent first. use after obtaining the organization id when needing paginated invoice data. | | `DNSFILTER_LIST_IP_ADDRESSES` | List IP Addresses | Tool to list user-associated ip addresses basic information. use when you need to retrieve paginated ip address records filtered by location or device after authentication. | | `DNSFILTER_LIST_MAC_ADDRESSES` | List MAC Addresses | Tool to list mac addresses associated with an organization. use when you need to retrieve basic mac address information, optionally filtered by organization or paginated. | | `DNSFILTER_LIST_NETWORKS` | List Networks | Tool to list all networks. use when you need to retrieve all network configurations for your organization. | | `DNSFILTER_LIST_ORGANIZATIONS` | List Organizations | Tool to list all organizations. use when you need to retrieve all organizations tied to the authenticated dnsfilter account. | | `DNSFILTER_SUGGEST_DOMAIN_THREAT` | Suggest Domain Threat | Tool to suggest a fqdn as a potential threat. use after identifying a suspicious domain to verify its threat categorization. | | `DNSFILTER_VALIDATE_AUTH0_JWT` | Validate Auth0 JWT | Tool to validate a jwt with auth0. use when you need to confirm token validity before making dnsfilter api calls. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Dnsfilter MCP server is an implementation of the Model Context Protocol that connects your AI agent to Dnsfilter. It provides structured and secure access so your agent can perform Dnsfilter operations on your behalf through a secure, permission-based interface. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites Before starting, make sure you have: - A Google API key for Gemini models - A Composio account and API key - Python 3.9 or later installed - Basic familiarity with Python ### 1. Getting API Keys for Google and Composio Google API Key - Go to [Google AI Studio](https://aistudio.google.com/app/apikey) and create an API key. - Copy the key and keep it safe. You will put this in GOOGLE_API_KEY. Composio API Key and User ID - Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs). - Go to Settings → API Keys and copy your Composio API key. Use this for COMPOSIO_API_KEY. - Decide on a stable user identifier to scope sessions, often your email or a user ID. Use this for COMPOSIO_USER_ID. ### 2. Install dependencies Inside your virtual environment, install the required packages. What's happening: - google-adk is Google's Agents Development Kit - composio connects your agent to Dnsfilter via MCP - python-dotenv loads environment variables ```bash pip install google-adk composio python-dotenv ``` ### 3. Set up ADK project Set up a new Google ADK project. What's happening: - This creates an agent folder with a root agent file and .env file ```bash adk create my_agent ``` ### 4. Set environment variables Save all your credentials in the .env file. What's happening: - GOOGLE_API_KEY authenticates with Google's Gemini models - COMPOSIO_API_KEY authenticates with Composio - COMPOSIO_USER_ID identifies the user for session management ```bash GOOGLE_API_KEY=your-google-api-key COMPOSIO_API_KEY=your-composio-api-key COMPOSIO_USER_ID=your-user-id-or-email ``` ### 5. Import modules and validate environment What's happening: - os reads environment variables - Composio is the main Composio SDK client - GoogleProvider declares that you are using Google ADK as the agent runtime - Agent is the Google ADK LLM agent class - McpToolset lets the ADK agent call MCP tools over HTTP ```python import os import warnings from composio import Composio from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") ``` ### 6. Create Composio client and Tool Router session What's happening: - Authenticates to Composio with your API key - Declares Google ADK as the provider - Spins up a short-lived MCP endpoint for your user and selected toolkit - Stores the MCP HTTP URL for the ADK MCP integration ```python composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["dnsfilter"], ) COMPOSIO_MCP_URL = composio_session.mcp.url, print(f"Composio MCP URL: {COMPOSIO_MCP_URL}") ``` ### 7. Set up the McpToolset and create the Agent What's happening: - Connects the ADK agent to the Composio MCP endpoint through McpToolset - Uses Gemini as the model powering the agent - Lists exact tool names in instruction to reduce misnamed tool calls ```python composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Dnsfilter operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ### 8. Run the agent Execute the agent from the project root. The web command opens a web portal where you can chat with the agent. What's happening: - adk run runs the agent in CLI mode - adk web . opens a web UI for interactive testing ```bash # Run in CLI mode adk run my_agent # Or run in web UI mode adk web ``` ## Complete Code ```python import os import warnings from composio import Composio from composio_google import GoogleProvider from dotenv import load_dotenv from google.adk.agents.llm_agent import Agent from google.adk.tools.mcp_tool.mcp_session_manager import StreamableHTTPConnectionParams from google.adk.tools.mcp_tool.mcp_toolset import McpToolset load_dotenv() warnings.filterwarnings("ignore", message=".*BaseAuthenticatedTool.*") GOOGLE_API_KEY = os.getenv("GOOGLE_API_KEY") COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") COMPOSIO_USER_ID = os.getenv("COMPOSIO_USER_ID") if not GOOGLE_API_KEY: raise ValueError("GOOGLE_API_KEY is not set in the environment.") if not COMPOSIO_API_KEY: raise ValueError("COMPOSIO_API_KEY is not set in the environment.") if not COMPOSIO_USER_ID: raise ValueError("COMPOSIO_USER_ID is not set in the environment.") composio_client = Composio(api_key=COMPOSIO_API_KEY, provider=GoogleProvider()) composio_session = composio_client.create( user_id=COMPOSIO_USER_ID, toolkits=["dnsfilter"], ) COMPOSIO_MCP_URL = composio_session.mcp.url composio_toolset = McpToolset( connection_params=StreamableHTTPConnectionParams( url=COMPOSIO_MCP_URL, headers={"x-api-key": COMPOSIO_API_KEY} ) ) root_agent = Agent( model="gemini-2.5-flash", name="composio_agent", description="An agent that uses Composio tools to perform actions.", instruction=( "You are a helpful assistant connected to Composio. " "You have the following tools available: " "COMPOSIO_SEARCH_TOOLS, COMPOSIO_MULTI_EXECUTE_TOOL, " "COMPOSIO_MANAGE_CONNECTIONS, COMPOSIO_REMOTE_BASH_TOOL, COMPOSIO_REMOTE_WORKBENCH. " "Use these tools to help users with Dnsfilter operations." ), tools=[composio_toolset], ) print("\nAgent setup complete. You can now run this agent directly ;)") ``` ## Conclusion You've successfully integrated Dnsfilter with the Google ADK through Composio's MCP Tool Router. Your agent can now interact with Dnsfilter using natural language commands. Key takeaways: - The Tool Router approach dynamically routes requests to the appropriate Dnsfilter tools - Environment variables keep your credentials secure and separate from code - Clear agent instructions reduce tool calling errors - The ADK web UI provides an interactive interface for testing and development You can extend this setup by adding more toolkits to the toolkits array in your session configuration. ## How to build Dnsfilter MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/dnsfilter/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/dnsfilter/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/dnsfilter/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/dnsfilter/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/dnsfilter/framework/codex) - [OpenClaw](https://composio.dev/toolkits/dnsfilter/framework/openclaw) - [Hermes](https://composio.dev/toolkits/dnsfilter/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/dnsfilter/framework/cli) - [LangChain](https://composio.dev/toolkits/dnsfilter/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/dnsfilter/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/dnsfilter/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/dnsfilter/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/dnsfilter/framework/crew-ai) ## Related Toolkits - [Apilio](https://composio.dev/toolkits/apilio) - Apilio is a home automation platform that lets you connect and control smart devices from different brands.

With a standalone Dnsfilter MCP server, the agents and LLMs can only access a fixed set of Dnsfilter tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Dnsfilter and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Google ADK? Yes, you can. Google ADK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Dnsfilter tools. ### Can I manage the permissions and scopes for Dnsfilter while using Tool Router? Yes, absolutely. You can configure which Dnsfilter scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Dnsfilter data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
